Yadav's Kathmandu-based company Explore Gadgets began as a YouTube channel in 2012, just after he'd completed his final year of school. The channel introduced his Nepalese audience to the latest technological gadgets, which are often difficult and expensive to access in Nepal. He's the only "YouTuber" in Nepal to receive a Silver Play Button award -- an award for reaching 100,000 subscribers -- from Youtube. The channel now has over 360,000 subscribers.

Surya Karki
Cofounder, Diyalo Foundation
Social Entrepreneurs

Karki is the founder of Nepal's Diyalo Foundation, which provides free education to children living in rural parts of the country. It also works to develop sustainable energy and farming by offering related services and training programs to rural residents. Born in rural Nepal to a single mother, Karki won a national scholarship at the age of eight and is currently working on his master's degree at Tsinghua University in Beijing.

The duo came up with their idea for an online apparel store -- the first of its kind in Nepal -- in 2012 while in college. Threadpaints quickly established itself as a trendy marketplace selling everything from t-shirts designed by hip local designers, to shoulder bags, watches and perfumes. And the brand remains true to its roots, raising funds through its 'T-shirts For Relief' campaign to help those affected in the aftermath of the devastating 2015 Nepal earthquake.
